-Subject: [PATCH] flow_dissector: Parse batman-adv unicast headers
-
-The batman-adv unicast packets contain a full layer 2 frame in encapsulated
-form. The flow dissector must therefore be able to parse the batman-adv
-unicast header to reach the layer 2+3 information.
-
-  +--------------------+
-  | ip(v6)hdr          |
-  +--------------------+
-  | inner ethhdr       |
-  +--------------------+
-  | batadv unicast hdr |
-  +--------------------+
-  | outer ethhdr       |
-  +--------------------+
-
-The obtained information from the upper layer can then be used by RPS to
-schedule the processing on separate cores. This allows better distribution
-of multiple flows from the same neighbor to different cores.
